I might be geting a JDM S5 turbo for my S4. And first off, it doesn't come with the WG actuator. Are the S4 and S5 actuators the same or compatible?



And are the water and oil lines all in the same place?



thanks, John

water and oil lines yes...



not sure about the wastegate question...

Not 100% sure if the wastegate actuator is the same, but you can most likely make it work. I know the JDM S5 turbo is identical to the USDM, so those actuators are the same.



Good luck!!



The water and oil lines are the same (as stated above).



Do you have an S5 manifold? You will need that as well it not.

Actuators are different, S-5 runs higher boost stock, and the arm has a bend in it, as opposed to the S-4 arm which is straight. I have a S-4 actuator for sale if you need one.

I know I need a manifold.



I was just needing a WG actuator. I got a good deal on the turbo. I can't pass it up!!



I'll have an S4 actuator from my current turbo so I'll see if I can figure someting out. Thanks.
